Professor says link to extreme weather sometimes overestimated but climate costs underestimated

Climate change is to blame for the majority of the heatwaves being recorded around the planet but the relation to other extreme events impacts on society is less clear, according to a study.

“I think on the one hand we overestimate climate change because it’s now quite common that every time an extreme event happens, there is a big assumption that climate change is playing a big role, which is not always the case,” said Friederike Otto, a climate change and environment professor at the Grantham Institute at Imperial College London, who was one of the lead authors of the research.

Climate-friendly practices can increase yields while improving ecosystem of farms, scientists say

Farmers could continue to produce high crop yields with far less use of artificial fertilisers if they adopted environmentally sustainable practices, an academic study has shown for the first time.

Techniques such as adding manure and compost to soils, growing nitrogen-fixing plants between crops, and cultivating a wide range of produce instead of sticking to the same crops, can all increase yields while protecting and improving the natural ecosystems of farms.

António Guterres says the world must turn the tide of rising sea levels, ocean heating, acidification and plastics pollution

The UN secretary general has declared that the world is in the middle of an “ocean emergency”, and urged governments to do more to restore ocean health.

Speaking at the opening of the UN ocean conference in Lisbon, Portugal, attended by global leaders and heads of state from 20 countries, António Guterres said: “Sadly, we have taken the ocean for granted and today we face what I would call an ocean emergency. We must turn the tide.”

Tim and Geli Harris to take agency to high court over groundwater removal for farming near protected wetlands

A couple are taking the Environment Agency to the high court in a landmark case to stop the abstraction of water damaging internationally important wetlands in the Norfolk Broads.

In a sign of the growing struggle over the allocation of scarce water resources in the dry south-east, Tim and Geli Harris are seeking to reduce the removal of groundwater to irrigate potatoes and other crops farmed next to three protected wetlands, including Hickling Broad national nature reserve.

Intestinal viruses such as rotavirus were found to be infectious for up to three days by attaching to microplastics, research shows

Dangerous viruses can remain infectious for up to three days in fresh water by hitchhiking on plastic, researchers have found.

Enteric viruses that cause diarrhoea and stomach upsets, such as rotavirus, were found to survive in water by attaching to microplastics, tiny particles less than 5mm long. They remain infectious, University of Stirling researchers found, posing a potential health risk.

Australia’s greenhouse gas emissions increased in 2021 as the country wound back Covid-19 lockdowns without taking significant steps to maintain a fall in carbon pollution recorded during the pandemic.

National emissions rose 0.8% – 4.1m tonnes of carbon dioxide – in the final full year of the federal Coalition government, according to government data released on Monday.

Australia’s new environment minister, Tanya Plibersek, has received an enthusiastic welcome in Lisbon at the UN ocean conference after flagging five new blue carbon projects and declaring that “under the new Australian government, the environment is back – front and centre”.

Plibersek opened her contribution at the conference by telling delegates: “For those of you who don’t follow Australian politics very closely, we’ve just had an election, there’s a new government, the whole world has changed.”

Penalties for peaceful action are now the same as for aggravated assault

Last Friday dozens of armed New South Wales police officers raided a camp near Sydney and arrested two environmentalists. One was Aunty Caroline Kirk, an Aboriginal elder. She was charged with “wilfully obstructing and intimidating police”.

“I can’t run, I can’t climb,” she said. “All I can do … is teach my culture. Why are they doing this?”

Games recognition could spur conservation action for the birds lovingly known as ‘rockatoos’ for their punk mohawks, vocal dexterity and percussive talents

They have shaggy crests and bright scarlet cheeks. They bow, sway, stamp their feet and spread their wings in a Jesus Christ pose, justifying their status. They whistle and whoop. Males even use their enormous beaks to fashion tree branches into drumsticks, which they use to beat on tree hollows approaching the breeding season.

They are palm cockatoos: the largest cockatoo in the world, weighing in up to 1.2kg – lovingly known as “rockatoos” for their punk mohawks, vocal dexterity and percussive talents. And Birds Queensland has officially nominated them as the mascot of the 2032 Brisbane Olympic Games, pointing out that previous Australian Olympic mascots have mostly been mammals.

19-year-old activist warns world faces ‘total natural catastrophe’ unless citizens take urgent action

Greta Thunberg has warned that the world faces “total natural catastrophe” unless citizens take urgent action as she made a surprise appearance at Glastonbury festival.

The 19-year-old activist led chants of “climate … justice” after delivering a rousing speech from the Pyramid stage which painted an apocalyptic picture of the future of the planet.

Although artist Aïda Muluneh had an itinerant childhood in Europe and America, she was born in Addis Ababa and is an expert in African photography. When charity Water Aid asked her to participate in a campaign highlighting water poverty, it was the women of Afar, northern Ethiopia, that she shot for her series Water Life, now included in Ekow Eshun’s new book of African art and photography, In the Black Fantastic (Thames & Hudson), published to coincide with a show at London’s Hayward Gallery. Muluneh was pleased that Water Aid wanted to use art for advocacy rather than reportage. “Our continent has many layers,” she says. “However, we have been at the mercy of the international media that does not show the complexities of our challenges. My approach has been to tell a story from my perspective, not based on cliches often covered by foreign photographers.”

Nearly 100 birds are being ‘headstarted’ to boost numbers as species vanishes from lowland England

An evocative peeping echoes across a large, sunny aviary. The distinctive call of the curlew comes from dozens of chicks, who strut through long grass squabbling over a much-prized worm.

The scruffy-looking chicks with the beautiful voices may be the best hope for the endangered species, whose numbers have halved in the past 25 years as it vanishes from lowland England.

Makers of the €250,000 Lightyear 0 hope to convince drivers it can be a viable climate-friendly alternative

Winding past the ochre-coloured plateaux of the Bardenas Reales natural park in northern Spain, Roel Grooten nudged me to take my foot off the accelerator.

The car continued to barrel down the open stretch of road, its speed dipping only slightly. “It keeps on going,” said Grooten, the lead engineer for the Dutch car company Lightyear, as we whizzed through the lunar-like landscape. “What you feel is nothing holding you back. You feel the aerodynamics, you feel the low-rolling resistance of the tyres, of the bearings and the motor.”

We must work with local communities to restore key species on a global scale if we are to tackle the climate and biodiversity crises gripping the world

There are few places in the world as majestic and full of wonder as Ecuador’s Galápagos Islands. From the rosy-hued pink iguanas on the northern rim of Wolf Volcano to the iconic Pinzón giant tortoise on Pinzón Island to the black-tipped reef sharks feeding off Floreana Island, we have both found boundless inspiration in exploring the islands that led Charles Darwin to develop his groundbreaking theory of evolution nearly two centuries ago.

We have both also witnessed a more recent rapidly evolving process in the Galápagos based on a shared vision of restoring the profusion of life that the archipelago is renowned for. This process is rewilding, a positive reframing for nature conservation. There is an idea that rewilding involves restoring nature at the expense of people, but we believe it is all about effectively integrating ourselves within the ecosystems that sustain us – to work with, rather than against, nature to create thriving and resilient ecosystems for the benefit of all.

I remember chilly trips to the beach in Fife, and my first visit to the Mediterranean. The association of heat with pleasure is hard to shake

I never saw my mother in a swimsuit, and I only once remember my father in one. In Fife in the 1920s, when both of them were young, sun-worshipping had yet to catch on. When my father swam, he swam in rivers, and then warmed himself up with a brisk towelling. My mother, who never learned to swim, would enjoy a day on the sands with tea brewed over a fire and sometimes a dance or two, if anyone had a squeezebox and the rain held off.

My parents remembered these things fondly during my childhood, when we might spend a summer afternoon on the local beach – it was only a 15-minute walk away – sometimes with relatives: cousins, a grandfather, uncles and aunts. Meteorology was less reliable then, and there seemed to be little question of adults “dressing for the weather” other than carrying a tightly folded plastic mac, which removed the precautionary need for a proper raincoat neatly arranged over the forearm.

Dutton’s choice to continue a policy of wrecking in energy highlights the challenge Albanese has in seeking to end the destructive decade

Every time I think my job is too hard and I need to retrain as a florist, I think of the poor officials who have served during the climate and energy policy wars – smart people held hostage by a public policy atrocity.

Back in July 2018 – when Malcolm Turnbull and Josh Frydenberg were attempting to land the national energy guarantee (Neg), wedged uncomfortably between post-truth rightwingers and state governments increasingly annoyed about being conscripted to an omnishambles – the Energy Security Board (ESB) ran out of patience.

We need synthetic fertilisers to produce enough food for the world’s population – there are no other alternatives yet

If water is the source of life, fertiliser is the source of scaleable food production.

The increasing cost of fertiliser is one of the largest contributors to a “cost-price” squeeze affecting the farmers of major agricultural products in Australia and globally.

Ocean campaigners say that a New Zealand fishing fleet that trawls for orange roughy in waters off Tasmania should be “sent back” in light of new data about the vulnerable species.

Orange roughy is an endangered deep-sea species which, under Australia’s environmental laws, can still be fished in approved fisheries.
